swift racing intake with ECU

[rajhothi]

I just installed my swift racing intake and ecu for a 99 GS400.
Sounds and feels amazing, but my check engine light has turned on after 20 miles of driving on the freeway..car still performs goods and has no problems..please help..

The main reason was the ECU wasn't properly tuned. The other reason could be some vacuum lines or MAF sensor were leaked/loose on the intake pipes. Try to disconnect the battery (both positive & negative) for 1/2 hour and reconnect it. If not, diagnose the code and see what it reads. I think Autozone can diagnose the code for free. Otherwise, you may get a manual and follow the instruction the find the code, or take your car to a shop.

My engine light and oil light comes on but my car still runs perfect and powerful...Bad or confusing Ecu reads from altering your stock parts causes that problem.. You can remove that bulb easily by removing your instrument cluster...
